Figure 4
Packing diagram of compound 1 viewed approximately parallel to the c axis (but rotated by ca 15° around the horizontal axis for clarity) in the region z ≃ 0.125, showing two chains of molecules parallel to the b axis. Dashed lines indicate H⋯Cl hydrogen bonds (thick) or Au⋯Cl contacts (thin). Hydrogen atoms not involved in hydrogen bonding are omitted. Atom labels indicate the asymmetric unit. Similar chains are formed in the regions z ≃ 0.375, 0.625 and 0.875. |
